' HYDRAULIC RAM.

To all whom it may concern Be it known that I, SIDNEY M. STE ENS, a citizen of the United States, residing at Prince George, in the county of Prince George and State of Virginia, have invented a new and useful Hydraulic Ram, of which the following is a specification.

It is the object of this invention to provide novel means whereby a hydraulic ram, supplied from one source, may be made ef- .fective as a means for elevating water from another source, without intermingling the water from the two sources.

Specifically, the invention aims to provide novel apparatus, actuable by a hydraulic ram, to elevate water from a source independent of the source whereby the ram is supplied; and to provide a novel form of valve for a hydraulic ram.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of theinvention.

In the drawings,-Figure 1 is a horizontal section, wherein sundry details appear in elevation; Fig. 2 is a vertical sectional elevation of the valve-proper and its connections; and Fig. 3 is a transverse section on the line AB of Fig. 2.

The invention includes a casing 1, comprising separable parts 2, bolted together at 3, or otherwise secured. Between the parts 2 of the casing, a diaphragm 4: is interposed, so as to divide the casing 1 into a compartment 5 and a compartment 6, the diaphragm a being a yielclable structure. Springs 7 are disposed in the compartments 5 and 6, the springs being secured at one end, as shown at 8, to the casing 1, the free ends of the springs 7 bearing against opposite faces of the diaphragm 4.

A pipe 9 communicates with the compartment 5, this pipe being provided with a T 10, receiving upon one side, a pipe 11, and upon the other side a pipe 12. There is a valve 1 1 in the pipe 11, and a valve 15 in the pipe 12, these valves permitting water to pass through the pipes 11 and 1.2 in t e Specification of Letters Patent.

direction of the arrows, but not in an opposite direction.

A pipe 16 communicates with the compartment 6, the pipe 16 opening into one side of a T 17, provided with a neck 18 for the reception of the pipe 16. The T 17 is supplied with a rectangularly positioned neck 19, into which a pipe 20 is threaded or otherwise secured. The end of the T which is opposite from the neck 19, is closed, as denoted by the numeral 31 in Fig. 2. The T 17 is equipped upon its upper side, with an upstanding neck 21, into which the valve structure hereinafter described, is inserted. This valve structure embraces a bushing 22,

threaded into the neck 21, the bushing 22 being provided with an opening 23. Preferably formed integrally with the bushing 22, and rising therefrom, are standards'24c', carrying at their upper ends a table 25. A valve stem, ordinarily a rod 26," is vertically slidable in the table 25, the rod 26 carrying at its lower end, a valve 27 adapted to seat against the lower end of the bushing 22.

The rod 26 is threaded, to receive superposed nuts 28, the nuts being located above the table 25. upon the rod 26, and disposed above the Mounted for reciprocation nuts 28, is the weight 29, ordinarily con- A securing device,

yielding and relieving the pressure upon the I valve 27, permitting the valve to drop. The flow of water through the pipe 20 will then be resumed, the operation above reterredto being the well known action of a hydraulic ram.

Water from a spring or other source of pure supply, enters the compartment 5 through the pipe 11, and the vibration of the diaphragm 4: will expel the water through the pipe 12, the valves 14 and 15 obviously cooperating to prevent a back-.

ward flowing of the water. The diaphragm t will be depressed by the water entering through the pipe 9, springs 7 assisting the diaphragm in it movement.

It frequently happens, in hydraulic ram operations, tr at the valve 27, when seated against the bushing 22, fails to fall into an open position, the operation of the ram, of course, immediately ceasing. To obviate this diiiiculty, the weight 29 has been provided. It will be seen that as the valve stem 26 moves upwardly, until the valve- 2? seats against the bushing 22, the weight 29 will be thrown upwardly. As the weight descends, it will impinge against the nuts 28, thus forcibly unseating the valve 27.: Obviously, the nuts 28 and the cotter pin 30 serve to limit the reciprocatory movement of the weight 29, the nuts 28 constituting a means for adjusting the travel of the valve 27.

Having thus described the invention What is claimed is 1. in a device of the class described, a casing having a seat; a stem vertically movable in the casing and having a valve upwardly movable to register in the seat; a weight freely slidable upon the stem; and a projection upon the stem, upon which the weight is supported when the valve is in open position, the projection engaging the casing to limit the opening movement of the valve; the engagement between the valve and the seat serving to lift the weight free from the projection, and the engagement between the weight and the projection, when the weight descends, serving to displace the valve from the seat.

2. In a device of the class described, a casing having a seat; a threaded stem vertically movable in the casing and having a valve upwardly movable to register in the seat; a Weight freely slidable upon the stem; a primary nut upon the stem; a lock nut upon the stem and engaging the primary nut, the weight being supported by the lock nut, when the valve is in open position, the primary nut engaging the casing to limit the opening movement of the valve, the en gagement between the valve and the seat serving to lift the weight free from the lock nut, and the engagement between the weight and the lock nut, when the weight descends,

serving to displace the valve from the seat.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
